The blades indicated by the {reference character 6 are formed independently of the knife, each blade having a head indicated at 7, which head is of a size to closely fit within the ends of the handle, in a' manner to prevent movement of the blade with re- Specification of Letters Patent. Patgntefl as may be may now be moved to either ement of parts and in v notches formed ad] a'cent, to-each-end thereo formed intermediate its ends and ac aptedf to accommodate the securing screwvtose-r of said heads havinggroovesto accommodetail, the-1 her having a centralportion normal 7 held "the right angled rportions of the spring Apr. 25, 1922. 1920.
